Ack. You bring back horrid memories of Statistics class.
Thanks for the numbers, anyway.
I’m sure you will agree that 7 cases is too small a sample to decide whether the US flu is actually less deadly.
Yes, but so is 14, since you would still have a 36% "probability of rejecting the null hypothesis", as the formula has it.
That is, if you were presented with 14 cases of a disease, and decided that your criterion for determining that the mortality was less than 7% was "no deaths". Then you would say this about an actual 7% mortality disease 36% of the time.
